WATER BAN DAG E.

SPECIFICATION forming part of Letters Patent No. 396,208, dated January 15, 1889.

Application filed April 2, 1888.

To all whom it may concern.-

Be it known that I, GEORGE P. I'IERNDON, a citizen of the United States, residing at \Vashington, in the District of Columbia, have invented certain new and useful Improvements in ater Bandages; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in devices designed to be applied to the body to modify the temperature thereof, and relates more particularly to that class in which the cooling or heating medium is caused to pass or flow through the pad or bandage. Devices of this character as heretofore constructed have been objectionable, for the reason that the water which passes through the tubes heats or cools, as the case may be, the body unevenly, owing to the fact that only a comparatively small portion of the tubes comes in contact with the body or with the covering of the tubes, which comes in contact with the body.

The object of my invention is therefore to overcome the objections heretofore found to exist and to construct.- a flexible water bandage so arranged that the heat or cold or the heating or cooling medium employed may affect the entire surface of the skin or body on which the bandage rests.

To the accomplishment of the above ends, and to such others as the invention may pertain, the same consists in the peculiar combinations and the novel construction, arrangement, and adaptation of parts, as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure l is a top plan of my improved bandage with the top broken away. Fig. 2 is a similar View showing a different arrangement Serial No. 269,316. (No model.)

nates the covering of the pad, which may be r of any suitablelight impervious material, although light rubber is preferred. This covering may be made of two or more pieces cemented or otherwise secured together, being provided at one end with an inlet or supply tube of rubber or other flexible material, as shown at a, and at another portion, preferably at the diagonal opposite corner, with an outlet-tube, b.

To prevent the inflation of the bag or covering, I stay the opposite sides thereof, which may be done in various ways, three of which are shown in the accompanying drawin I11 Fig. 1 a flexible tube, B, is coiled around within the covering and cemented or otherwise secured to the inner surface of the said covering, so as to hold the sides at a regulated distance apart.

In Fig. 21 have shown a plurality of short tubes, 0, arranged as shown, although the arrangement is immaterial, the said tubes being secured to the sides of the covering, while in Fig. I have shown the sides held at the proper distance apart by means of the vertical short tubes (1, any desired number of which may be employed.

It will be seen that by these arrangements of the parts the bag cannot be inflated by the water, so that the weight of the bandage cannot be increased beyond a given limit. In addition to their function, as a means of keeping the sides of the bandage at a regulated distance apart, these tubes have the additional function of aiding in the heating or cooling of the temperature of the patient, and for this purpose they are each and all, or nearly all, provided with perforations, as shown at e in the several figures. These per- 't'orntions allow the water to flow through the tubes, and in this way the whole exterior surface of the bandage is kept at an even temperature, the water being both in the tubes and in the spaces between the same.

The device is flexible and may be made of any desired shape or size to suit the purposes for which it is designed to be used.

I deem it important; that the tubes be arranged within the outer covering, so that the outer walls of the bandage shall be t'tmned by the covering A, wherelryl obtain 2th increased heating or cooling surface all in the same plane.
